[strongSwan] initialzing EAP TLS peer with a different IDi than the IDi used in teh first IKE AUTH message

[Ravi Kanth Vanapalli]

Dear Andreas,
   Looks my issue is not solved yet.
  I have modified the  identity with the statement below
(1)     auth->add(auth, AUTH_RULE_EAP_IDENTITY, id2);

But still EAP-TLS is looking for Idenity set with

1) auth->add(auth, AUTH_RULE_IDENTITY, id1);

Can you please help me with this issue.

Thanks,
Ravikanth
